Have you selected "line-in" as the default in XP's recording devices ? ...

For the reverb and compression, should I apply it all the way across the board, or just to select channels? what's normal? IMO I'd try to avoid applying reverb to the percussion if you have the option. IMO dynamic range compression should be applied to the final mix just before you convert to MP3, ...

Johnny B better ? (a more mono mix, with dynamic range compression, and hint of reverb) ...

The bitrate on the recording of "Tequila Sunrise.mp3" @ 128Kbps is too low for a 44100Hz stereo recording: the high frequencies (above 16KHz) have been lost as a result ... Bit rate on 'Tequila Sunrise,mp3' is too low, use 256Kbps.png BTW you could chop off the hummy bit at the start of Te...

... an MP3 player, not much better probably! The sample rate and bit depth can be adjustable on such devices, both affect the sound quality. A sample rate of 22050Hz and a bit depth of 8 provides good clear speech recordings. [some of the codec options on such devices, like ADPCM , only have a bit ...

... in Audacity now there are two audio tracks, but only the second one shows waves, while the first one doesn't show any waves. It does show waves but they're very small, you need to amplify the secret female voice track to make the waveform more obvious ... Split the stereo to mono , select the u...

Goldwave is another audio processing program which has good noise reduction (Windows only).
In the past Goldwave offered a fully-functional free-trial version which operates for 1000 operations,
(previewing / applying an effect counts as 1 operation).

Would you recommend removing noise from the original Audacity project and then exporting to mp3, or just removing noise from the mp3? Conversion to MP3 should be the last stage in the process, MP3 s a delivery format. Apply the noise reduction to a copy of the project, i.e. don’t overwrite the orig...
